feasibility of an online, self-administered cognitive screening tool in older patients undergoing ambulatory surgery

Conditions: Delirium in Old Age; Alzheimer Disease; Mild Cognitive Impairment; Neurocognitive Disorders

Summary: delirium is common in older adults after inpatient surgery and may be associated with cognitive decline. advances in surgical and anesthetic techniques have led to increasing numbers of older adults undergoing surgery on an outpatient basis. however, few studies have investigated cognitive disorders of older adults before or after ambulatory surgery. increased age and pre-existing cognitive impairment are strong risk factors for cognitive decline after surgery, yet older adults are not screened for cognitive impairment before surgery. existing screening tools require specially trained staff for test administration and in-person testing. virtual cognitive screening has not been evaluated in surgical patients. in this study, investigators will determine the feasibility of using cogniciti's brain health assessment (bha) - a validated online cognitive screening tool that can be self-administered from a patient's home before surgery - to screen older adults before ambulatory surgery.

older adults (≥60 years of age) are the fastest growing age group in canada, and by the year 2026, will constitute more than 1 of every 5 canadians. world-wide, about 703 million people are ≥65 years of age, and this number is projected to double to 1.5 billion in 2050. higher life expectancy and advancements in anesthetic techniques have led to more older adults with high burdens of co-morbidities to undergo ambulatory surgeries. approximately 40-53% of all surgeries performed are on patients \>65 years of age. neurocognitive disorders (ncd) are common in the community with 14-48% of those \>age 70 years suffering mild cognitive impairment (mci). impairments in cognitive ability are the most common complications in older adults undergoing major surgery. these impairments include 1) delirium (which may last up to 7 days after surgery), 2) delayed neurocognitive recovery (cognitive decline up to 30 days after surgery) 3) neurocognitive disorder (postoperative) mild or major (30 days to 12 months after surgery). the decline in executive function, memory, and other cognitive domains may last for weeks to months after surgery. while most patients recover from cognitive impairment, a small minority of patients have persistent impairment. older adults who are diagnosed with pnd have longer hospital length of stay, are less likely to be discharged home, increased health care costs, and a higher incidence of mortality at one year after surgery. investigators hypothesize that it is feasible to utilize the bha to screen for ncds, and to assess cognitive changes in elderly patients undergoing elective ambulatory surgery.
